Yes, some kids these days pick the autism label when they probably shouldn't, but that does NOT mean you get to shit on actually disabled people

You shouldn't shit on anyone, but you do raise a good point: how do you know who the actually disabled people are?

If some people who claim autism offer as evidence experiences that almost all neurotypical folks can relate to, people are going to be skeptical. You can call them bigoted assholes, but you're unlikely to shame anyone into suspending their skepticism.
